The alignments in your changes do not match the exact specifications of the Figma file. The Figma file provides the precise alignments that need to be followed.

1. On the sidebar, the border should have a border-radius of 10px.
2. On the navbar, the bottom border does not fully cover the text—it is at 85% of the text width. Additionally, there should be some padding at the bottom of the text.

Due to these issues, your PR cannot be accepted. You need to make the changes as specified in the Figma design.

For future PRs, please share your work in the frontend-discussion channel on Discord before raising the PR. Include:

• The issue number.
• The issue title.
• The changes you made.
• The context of your work.

This approach will help both of us better understand and review your contributions before submitting a PR.
